【RPM 2621S-01 Full Exhaust Muffler RPM-67Racing Stainless Steel φ67×300 CB400SF VTEC SPEC1/2/3 Road Legal Rokunana Racing RPM】
■Product Description
The RPM-67Racing is an exhaust system born from approximately 300 meticulous handcrafted processes and TQC (Total Quality Control). It is an original muffler brand launched in 1998 as an F-TYPE replica model, without making significant changes to the appearance of the RPM-4in2in1 F-TYPE, which was manufactured until 1989, or to the internal structure of the silencer, which is crucial for sound quality.

■Detailed Description
●Exhaust Pipe
The adopted 4-in-2-in-1 manifold system offers higher exhaust synergy than a 4-in-1 manifold system in a 4-cylinder engine, and significantly contributes to producing a high-quality sound.
The material used is steel (STKM11A mechanical structure carbon steel pipe). Each component is carefully polished by skilled craftsmen before undergoing a high-quality plating process, providing both excellent aesthetics and weather resistance.
●Silencer
The φ67×300 silencer, which produces a unique and exhilarating racing sound, achieves maximum sound dampening with minimal exhaust resistance by having a completely double-layered internal structure.
Furthermore, its lightweight and compact body possesses high rigidity and excellent resistance to vibrations under harsh operating conditions.
●Silencer Outer Cover Lineup
The outer cover material is available in the following three types:
・Aluminum alloy A6063S
・Stainless steel SUS304/mirror finish
・Titanium TP270
●Component Configuration
This is a full exhaust muffler consisting of a total of 5 parts: "4 front exhaust pipes (from the engine to the collector)" and "1 tail ASSY (from the collector, including the silencer)".
●Installation Status
It is fixed to the vehicle at two points: the engine exhaust port and the tail stay.
When installing at the engine exhaust port, use the free flange (exhaust holder) included with this product.
※Exhaust gaskets are not included, so you will need to purchase them separately.
●About Silencer Structure Requirements
The RPM-4in2in1 F-TYPE allowed for the removal and attachment of the inner silencer built into the silencer for race use and repair purposes. However, many users would ride on public roads with the inner silencer removed, which went against the original intention. Therefore, RPM now welds the inner silencer in place.
※Sound adjustment and back pressure adjustment are not possible in the new factory-shipped state.
